Comments of chapter undefined of Awakening @end of the world

I really can't feel any type of realism in mc's 23rd century Earth and it feel like some child future prediction who have no idea about how world actually works. sorry for it. still a nice story. it's just no realism here. way too advance science in 23rd century. way too different culture and way of thinking in just 100 years. can't believe mc doesn't heard about a word "magic" before. world is suffering from population collapse(in reality most developed country and many developing country) while this story says we are out of resource in just a century in our whole solar system(that's just buslhit and childish)
